When people scurtenise the world, they are compering the phenomena to information they gatherd in their NMOs. A contrediction is detected by the ACC, which activate system 2 in order to solve the contrediction. system 2 will oprate also when a novel task or complext rational task will presnt themselves.
When in stress, the FFFF system is put action. It seems that it inhibit ACC activation, thus, closing the actvation of system 2, and probably closing also jeneral empathy. The FFFF system may open a process to strength "famely" relations to strength group cohesion.
